The TCL language an Tk toolkit, even alone, offer many benefits: they're easy to learn, capable of producing good interfaces quickly, great for prototyping applications, and they are infinitely customizable. But of the greatest strengths of TCL/Tk is the range of extensions written for it . Now you can read about the most popular and robust extensions, freshly documented with the classic O'Reilly quality by the extension authors themselves, with encouragement in a foreword by Tcl/Tk creator John Ousterhout. With Tcl/Tk extentions, you can: - Write robust object-oriented programs - Produce complex inerfaces with one-line commands - Lay out graphs and tables - Display 3D graphics with rich textures - Interact with Oracle and Sybase databases - Network over sockets and remote procedure calls - Create collaborative multi-user-environments - Automate programs that call for human users - Use complex data structures and UNIX systems calls - Embed Tk calls in C programs - Display tree structures - Replay and prototype user interactions -Tcl/Tk documents all these extensions - in an eminently readable and usable form by the people who created them - and contains information on configuation, debugging, and other important tasks. This book comes with a CD-ROM that includes Tcl/Tk, the extensions, and other tools documented in the text both in source form and as binaries for Solaris and Linux
